"One of my favorite covers that I created was Kristen Stewart. We transformed her." - Stefano Tonchi with @ManRepeller at Apple Spho— W magazine (@wmag) February 12, 2015
Designer Jason Wu at the W's Magazine 'Shooting Stars' exhibition in Los Angeles
WWD: What's your favorite pic?
JW: It’s hard to choose. Gotta love the Kristen Stewart one. I mean, that’s beautiful but there’s so many to choose from, and of course the Margot Robbie because I’m biased.
